BUSWELL ADJUSTABLE CLAMP.

To all whom it may concern:

Be it known that we, EUGENE BUSWELL and THOMAS GAsoAnnN, Jr., citizensof the United States of America, and residents of Waterloo, Blackhawkcounty, Iowa, have in vented certain new and useful Improvements inAdjustable Clamps, of which the following is a specification.

Our invention relates to improvements in adjustable clamps, and theobject of our improvement is to provide means for clamping asprocket-rim to a carrying-wheel, removably, and adapted to be adjustedto be secured at will to the spokes of carryingwheels where such spokesare of different dimensions, and also adapted to be clamped detachablyto any part of the edge of such a sprocket-rim. This object we haveaccomplished by the means which are hereinafter fully described andclaimed, and which are illustrated by the accompanying drawings, inwhich:

Figure 1 is a side elevation of a sprocketrim secured to the spokes of ametal carrying-wheel, wherein the spokes are of relatively smalldiameter. Fig. 2 is a side elevation of a sprocket-rim secured to thewooden spokes of relatively large diameter of an other carrying-wheel.Fig. 3 is an enlarged broken detail showing our improved clamping-meansas used to connect a sprocket-rim to a wooden spoke of relatively largediameter. Fig. 1 is an under plan view of said clamping-means. Fig. 5 isa side elevation, broken, of our improved clamping-means as used tosecure a sprocket-rim to a metal spoke of a relatively small diameter.

Similar numbers refer to similar parts throughout the several views.

()ur adjustable clamp consists of the following coacting parts orelements. 15 and 8 are bodies which are used as clamping-members tosecure between them the inner edge of a sprocket-rim 2. The opposed lugs16 and 11 of said members respectively are adapted to contact when themembers are secured to the rim 2, the rim being held between the upperpart of the member 8 and the lug 19 on the member 15, the lug 19engaging and resting between the ribs. 17 and 18 on said rim. The mainportion of the body 15 extends at an angle to the sprocketrim 2 and hason its outer end a relatively large concavity 20 adapted to fit aboutone side of a large spoke 7, and with a; small Specification of LettersPatent.

concavity 13 adapted to fit one side of a relatively smaller spoke 6.The side edges of the body 15 are grooved, and the body 8 is orificed,to receive the limbs of a U-bolt 3, said limbs being exteriorly threadedat their extremities to receive the nuts 10. When it is desired tosecure the sprocketrim 2 to certain of the large diameter wooden spokes7 of a carrying-wheel 5, the spoke 7 is simply clamped between theconcave end 20 of the body 15 and the inner curve of the U-bolt 3.

l Vhen it is desired to adjust the clampingdevice to cause it to fit asmaller diameter spoke 6 of a carrying-wheel 1, a clampingmember 12 isinserted detachably in the inner curve of the U-bolt 3. This member 12has a curved grooved outer edge to fit and conform to the curve of saidU-bolt, while it has a projection 17 extending toward the sprocket-rim,the end of the projection being provided with a concavity 14 ofrelatively small size adapted to grasp the outer side of the spoke 6,the inner side of said spoke being grasped by the oppositely locatedconcavity 13 in the end of the body 15. In either case, when the nuts 10have been placed on the ends of the U-bolts after the latter have beenpassed through the orifices in the clamping-member 8, the inclosed spokeis held securely as well as the inner edge of the rim 2. Thisclampingmeans is peculiarly adapted for use in connection with thedriving-mechanism of a removable receptacle manure spreader, since thedriving-sprocket rim 2 may be secured at Will to a carrying-wheel ofeither a set of running-gear fitted with earrying-wheels 1 having smallmetal spokes, or to the larger wooden spokes 7 of a carrying-wheel 5 ofanother set of running-gear.

In Fig. l, the clamping-device is shown as used to secure thesprocket-rim 2 to the metal spokes 6 of a carrying-wheel 1, wherein thespokes are eighteen in number, staggered, and the clamping-connectionsare made to spokes on the inner side of the wheel alternately, exceptthat on account of the uneven number of inner staggered spokes, two ofthe clamping-connections are secured to adjacent spokes of the innerseries. In this use, the clamping-member 12 has been used to hold thespoke 6 of a relatively small diameter.

In Fig. 2, the clamping-devices are used on alternate spokes of largerdiameter, there being fourteen wooden spokes 7 of the wheel 5, and inthis case the clamping-member 12 is removed, since the inner curve ofthe U- bolt 3 serves to grasp the outer side of the spoke, inconjunction with the concavity 20 of the body 15.

It will be observed, that our clampingdevice is secured to the inneredge of the sprocket-rim 2 by clamping solely, the limbs of the U-bolt 3not passing therethrough, as in some other devices. In consequence ofthis, the clamping-members 8 and 19 may be secured to any portion ofsaid rim, which enables the devices to be used, no matter how manyspokes are in the carrying-wheel, and without regard to their differentdistances of spacing apart.

The device is thus adaptable first to dii it'erent diameters of spokes,and second, to be secured on any part of a sprocket-rim as desired whenit is necessary to locate them properly to be opposite certain spokes ofcarrying-wheels without regard to the differing numbers of spokes insuch wheels.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is:

1. In combination, a carrying-wheel, a sprocketor gear-rim, and adetachable connection between said sprocket-rim and a spoke of saidcarrying-wheel, comprising clamping-members adapted to grasp said rimbetween them rcmovably, a U -bolt with limbs detachably securing saidclamping members together, and detachable engagingmeans seated in theloop of said bolt and adapted to grasp one side of said spoke, one ofthe aforesaid clamping-members having a counterpart seat for the otherside of said spoke.

2. In combination, a carrying-wheel, a sprocketor gear-rim, and meansfor detachably securing said sprocket-rim to a spoke of saidcarrying-wheel, comprising clampingmembers adapted to grasp said rimbetween them removably, a U-bolt with limbs detachably securing saidclamping-members together, and detachable engaging-means between thelimbs of said bolt adapted to hold a spoke of said carryingwheel betweenthem, said engaging-means having one separable part provided with a seatof small dimensions, and a counterpart member having seats of both smalland larger dimensions,

located opposite to the said separable part and to the loop of saidU-bolt.

3. I11 combination, a carrying-wheel, a sprocketor gear-rim, detachableclamps having separable opposed jaws adapted to grasp and be slidablyadjustable along said rim, adjustable means connected between saidclamps and located near but inside of the inner edge of said rim fordetachably clasping the clamps together upon said rim, and other clampsconnected to said firstmentioned clamps, and adapted to be detachablysecured to said carrying-Wheel.-

et. In combination, a carrying-wheel, a sprocketor gear-rim, detachableclamps adapted to grasp said rim, and separable clamps connected to thefirst-mentioned clamps, said second-mentioned clamps adapted to besecured to a spoke of said carryingwheel of a relatively small diameter,one of the parts of the second-mentioned clamps being removable to adaptthe clamps to be secured to a spoke of relatively large diameter.

5. In combination, a carrying-wheel, a sprocketor gear-rim, clampshaving separable opposed jaws adapted to detachably grasp and beslidably adjustable along said rim, adjustable means connected betweensaid clamps and located near but inside of the inner. edge of said rimfor detachably clasping, the clamps together upon said rim, and meansconnected to said clamps adapted to secure the latter to saidcarrying-wheel. v
